Deepak Singh

I’m a Software Engineer who turns complex requirements into reliable, high-performance products across backend services and user-facing dashboards. I enjoy collaborating closely with product and marketing teams to improve onboarding, retention, and overall user experience.

At Nitor Infotech (an Ascendion company), I helped redesign user onboarding and drove retention and UX improvements by 40%. I also mentored 6 junior engineers, delivering structured training that increased team velocity by 90%, and I built a centralized data analytics solution that enabled 200+ published papers through better access across universities.

I’ve architected scalable backend systems using Node.js, Express.js, and NestJS aligned with RESTful and microservices principles, achieving 99.99% uptime for 500+ concurrent users. I optimize performance by integrating Redis queues (Bull) for background task processing and by applying Redis caching and query optimization to cut response times by 90%.

I’m equally focused on secure, maintainable delivery: I integrated secure payment gateways with transaction workflows and webhook handling (cutting fraud attempts by 60%), and I automated deployment workflows with CI/CD and blue-green deployments to reduce manual errors and save 10 hours per week. I also build React.js dashboards for real-time reporting and develop automated testing and infrastructure components to keep releases fast and dependable.
